> Subject: [gmx-users] many charges within one atom
> Hi everybody,
> I'm trying to run simulations with a charge distribution within one single atom. Is there a way to create a molecule, in which every atom has a charge distribution - more charge points at one atom.
You can construct charges at fixed sites using virtual sites,
or have them moving around (polarizable) by using shells attached to a spring.
Both methods are described in the manual.
> Is it possible to run a simulation in a polarizable electric continuum in stead of simulating the molecules of the solvent?
I don't see how you can easily make a polarizable contiuum.
If it is possible at all, a very complex electrostatics solver will be required.
